Reconcile three ARR figures and name the one for the board

About this exercise

Three sources give different ARR figures. Use the most recently dated source as the reference. Build a table with the header Source | ARR ($M) | Date | Difference vs reference ($M) and one row per source, sorted by date, earliest first. Show differences with a sign. Add Check in the Difference cell when a source differs by more than 0.3. Then add the exact last line: Use for the board: $18.4M (Finance close, Nov 7). Plain text, under 100 words.

Common mistakes when you ask AI for this

• Choosing the biggest number. The AI treats the CRM as the reference. Try: Say: "Use the most recently dated source as the reference."
• Wrong check flag. The AI flags the deck too. Try: Say: "Check only when a source differs by more than 0.3."
• Wrong sort. The AI sorts by value. Try: Say: "Sort by date, earliest first."
• Missing exact last line. The AI adds a recommendation paragraph. Try: Say: "End with the exact line."
• Markdown. The AI bolds the Check. Try: Say: "Plain text."
• Trusting the AI to count words. AI is bad at counting. Ask for a total word limit and it often lands over it. Try: Cap each part instead, for example: "each line under 15 words."
